Japan's first weather radar
JRC's new solid-state architecture integrates an advanced signal processing technology that detects and displays information at a new level.
These dedicated signal processing circuits are producing higher capability than a klystron radar or a magnetron radar, greatly exceeding detection performance.
Transmission power of the solid-state transmitter is small compared to the tube type transmitter, but by using the pulse compression technique, it is possible to impart the transmission capacity comparable to that of the tube type radar.
Low maintenance cost
The radar integrates a highly reliable solid-state transmitter in place of a life limited klystron or magnetron. The solid-state radar provides higher reliability and performance and will keep maintenance costs to a minimum.
Solid-State Power Amplifier (C-band)
Fully solid state and high reliability.
Provides a wide range of applications for disaster prevention and research, and meteorological analysis
By using the newest signal-processing algorithm and data-processing algorithm, it is possible to observe a weather echo with high precision quantitatively in real time.
